Study Notes
Experiment Overview
- Sam conducted an experiment to identify the optimal power and time settings for microwave popcorn.
- The objective was to achieve an average of fewer than 8% unpopped kernels.
Optimal Settings
- The best settings were determined to be power level 9 for a duration of 4 minutes.
- These settings were tested further by popping 8 additional bags of popcorn randomly to validate results.
Quality Assessment
- The percentages of unpopped kernels from the additional bags were recorded as follows:
- 3.7%
- 10.7%
- 4.6%
- 5.8%
- 6.1%
- 9.9%
- 12.3%
- 4%
Hypotheses Formulation
- Null Hypothesis (Ho): The average percentage of unpopped kernels (u) is equal to 8%.
- Alternative Hypothesis (Ha): The average percentage of unpopped kernels (u) is less than 8%.
